(TBNA) (trans-brong'kē-ăl nē'dĕl as'pir-ā'shŭn)
1. Biopsy of a structure or region adjacent to a bronchus by means of a needle introduced through a bronchoscope.
2. Diagnostic procedure used in cytology and histology studies of intrathoracic and respiratory disease.

transbronchial needle aspiration

Abbreviation: TBNA
A method of sampling abnormal tissue masses found in the mediastinum. A needle is guided into the mass during bronchoscopy, and cells are dislodged with a sawing motion. Suction is applied to gather specimens. TBNA is typically used to determine whether the mass represents a malignancy, such as a bronchogenic carcinoma or lymphoma.
